小豆生长发育规律研究——Ⅸ.不同株型小豆花、荚分布模式

根据植株形态将小豆划分为:(1)直立型、(2)半蔓生型、(3)蔓生型三种类型。研究表明,小豆植株的花、荚主要分布于植株中、下部,而株型间仍有明显差异。在南京夏播条件下,结荚率直立型最高,成荚数瘦弱型主要依主茎,而紧凑型、扇型为主茎与分枝并重;半蔓生型、蔓生型主要依靠分枝上花成荚,且蔓生型结荚率较低。

Research for Growth and Developmental Rhythm of Adzuki Bean——Ⅸ. The distribution pattern of flower and pod of different plant

Accoding to plant torm adzuki bean was divided into three types,theyare(1)erect stem. (2)half-trailer. (3)trailing plant.Research indicates that the flower andpod of adzuki bean plant dispersed over middle ow position,and there are notable diversityamong plant types.In Nanjing summer seeding the pod setting rate of erect stem type ishighest.The number of pod setting of the thin and weak types depende on their main axisbut compact and fan types depende on their main axis and branch;Haif-trailer and trailingdepend on flower and pod of branch.The rate of pod setting of trailing plant is lower thanother types.Planting date has more influence on rlower、pod number and its space distri-bution of adzuki bean.
